Description

Technical Field

[0001] The utility model relates to the field of monitoring, in particular to a device for adaptively adjusting and uploading the state of a multi-spectral device. Background Art

[0002] The multi-spectral device includes a visible light component, an infrared thermal imaging component, and a laser illumination component. The states are divided into two types: one is whether it is powered on, and the other is whether it is normal, and these two states are uploaded. The multi-spectral device needs to ensure the integrity and clarity of the monitoring screen all day long. The current monitoring devices will work when powered on, without distinguishing between power-on and power-off control, nor between day and night. When powered on, it is necessary to check whether each component is normal in real time and upload the status. This working method will undoubtedly increase the usage rate and occupancy rate of the device and shorten the service life of the device. In fact, in the daytime environment, the single visible light is sufficient to meet the monitoring needs, and there is no need to turn on the infrared thermal imaging. At night, the visible light is not sufficient to meet the monitoring needs, and the infrared thermal imaging or laser illumination can be turned on to meet the needs at night. Therefore, according to the changes in the environment and temperature, a device that can adaptively adjust the working state of the components and upload the status type is needed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a device for adaptively adjusting and uploading the state of a multi-spectral device, which can adaptively adjust the working state of the components and upload the status type according to the changes in the environment and temperature, reduce the usage rate and occupancy rate of the device, and extend the service life of the device.

[0004] In order to solve the above technical problem, the technical solution adopted by the utility model is: a device for adaptively adjusting and uploading the state of a multi-spectral device. The multi-spectral device includes a visible light component, an infrared thermal imaging component, and a laser illumination component, and includes a photosensitive sensor, a temperature sensor, a serial port detection circuit, an MCU, and a power control circuit. The photosensitive sensor is installed on the multi-spectral device and is used to detect the brightness of the environment where the multi-spectral device is located. The temperature sensors are respectively installed on the visible light component, the infrared thermal imaging component, and the laser illumination component, and are used to detect the temperatures of the visible light component, the infrared thermal imaging component, and the laser illumination component. The serial port detection circuit is respectively connected to the TTL serial ports of the visible light component, the infrared thermal imaging component, and the laser illumination component. Each component has a corresponding status query instruction. By sending an instruction to the component through the TTL serial port, the component will feedback the corresponding status to the MCU, which is used to detect the status of the visible light component, the infrared thermal imaging component, and the laser illumination component. The photosensitive sensor, the temperature sensor, and the serial port detection circuit are respectively connected to the input end of the MCU, and the power control circuit is connected between the output end of the MCU and the power supply end of the visible light component, the infrared thermal imaging component, or the laser illumination component.

[0005] Further, the power control circuit includes a triode Q2 and a MOS transistor Q1. The output terminal of the MCU is connected to the base of the triode Q2 through a resistor R5. +12V is connected to the collector of the triode Q2 through a resistor R3. And the collector of the triode Q2 is connected to the gate of the MOS transistor Q1 through a resistor R4. The emitter of the triode Q2 is grounded through a resistor R8. The source of the MOS transistor Q1 is connected to +12V. The drain of the MOS transistor Q1 is connected to the power supply terminal of the visible light component, the infrared thermal imaging component or the laser lighting component.

[0006] Further, a parallel-connected capacitor C3, C6 and an indication circuit are connected between the drain of the MOS transistor Q1 and the ground. The indication circuit includes a series-connected resistor R9 and a light-emitting diode D2. One end of the resistor R9 is connected to the drain of the MOS transistor Q1. The other end of the resistor R9 is connected to the positive electrode of the light-emitting diode D2. The negative electrode of the light-emitting diode D2 is grounded.

[0007] Further, a serial port uploading circuit is also included. The serial port uploading circuit is connected to the serial port tool of the upper computer through a USB to TTL converter. The component status is obtained by querying the TTL of the serial port detection circuit. The information returned is 0 for normal and 1 for abnormal. The MCU will record the power-on flag as 1 and the power-off flag as 0. For example, for the visible light module, when powered on without abnormality, it is 01, 00; when powered on with abnormality, it is 01 01; when powered off, it is 00 00. The same applies to other modules. The serial port uploading circuit is connected to the upper computer and is used to transmit the status of the multispectral device to the upper computer.

[0008] Further, the number of photosensitive sensors is 1, the number of temperature sensors is 3, and the serial port detection circuit has 3 channels.

[0009] The beneficial effects of the present utility model: The present utility model adds one photosensitive sensor, three temperature sensors, three power control circuits, three serial port detection circuits and one serial port uploading circuit. Adaptive state adjustment: The photosensitive sensor is used to judge whether it is day or night; the power control circuit is used to control the power supply of the visible light, infrared thermal imaging and laser lighting components.

The other serial port uploading circuit is used to output the status of the entire device (whether powered on or normal) externally.

[0010] Traditional devices have a great deal of waste in the utilization and use of resources. Although the cost of this device has increased slightly, compared with the improvements in other aspects, the cost can be ignored. Adaptive state adjustment and segmented use of visible light components and infrared thermal imaging components increase the service life of the device, reduce power consumption, reduce the failure rate, and reduce operation and maintenance costs; Adaptive state upload, key detection of abnormal components, and corresponding state upload should also be focused on. Components without abnormalities can be temporarily not uploaded or the upload frequency can be reduced, improving the utilization efficiency of resources, quickly and effectively detecting abnormal nodes, and making timely and effective countermeasures.

[0017] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] This embodiment discloses a device for adaptively adjusting and uploading the state of a multi-spectral device, including a photosensitive sensor, a temperature sensor, a serial port detection circuit, a serial port upload circuit, an MCU, and a power control circuit.

[0020] In this embodiment, the number of photosensitive sensors is 1, the number of temperature sensors is 3, and there are 3 serial port detection circuits. One photosensitive sensor is installed on the multispectral device to detect the brightness of the environment where the multispectral device is located. The three temperature sensors are respectively installed on the visible light component, the infrared thermal imaging component, and the laser illumination component to detect the temperatures of the visible light component, the infrared thermal imaging component, and the laser illumination component. The three serial port detection circuits are respectively connected to the TTL serial ports of the visible light component, the infrared thermal imaging component, and the laser illumination component. Each component has a corresponding status query instruction. The MCU sends instructions to the components through the TTL serial port, and the components will feedback the corresponding status to the MCU to detect the status of the visible light component, the infrared thermal imaging component, and the laser illumination component.

[0021] As Figure 1 shown, the MCU uses an STM32 series single-chip microcomputer. Combined with Figure 2 , the input terminals of the MCU are respectively connected to the photosensitive sensor and the temperature sensor through connectors J2, Q5, Q6, and Q7. The serial port detection circuit is connected to the serial ports UART_TX and UART_RX of the MCU. The power control circuit is connected between the output terminal of the MCU and the power supply terminals of the visible light component, the infrared thermal imaging component, or the laser illumination component. There are also 3 power control circuits, namely the power control circuit for the visible light component, the power control circuit for the laser illumination component, and the power control circuit for the infrared thermal imaging component.

[0022] As Figure 3 shown, the power control circuit for the infrared thermal imaging component includes a triode Q2 and a MOS tube Q1. The output terminal of the MCU is connected to the base of the triode Q2 through a resistor R5. +12V is connected to the collector of the triode Q2 through a resistor R3, and the collector of the triode Q2 is connected to the gate of the MOS tube Q1 through a resistor R4. The emitter of the triode Q2 is grounded through a resistor R8. The source of the MOS tube Q1 is connected to +12V, and the drain of the MOS tube Q1 is connected to the power supply terminal of the visible light component, the infrared thermal imaging component, or the laser illumination component.

[0023] Furthermore, a parallel-connected capacitor C3, C6, and an indication circuit are connected between the drain of the MOS tube Q1 and the ground. The indication circuit includes a series-connected resistor R9 and a light-emitting diode D2. One end of the resistor R9 is connected to the drain of the MOS tube Q1, the other end of the resistor R9 is connected to the positive electrode of the light-emitting diode D2, and the negative electrode of the light-emitting diode D2 is grounded.

[0024] Figure 4 And Figure 5 are respectively the schematic diagrams of the power control circuits for the visible light component and the laser illumination component, and their structures are the same as those of the power control circuit for the infrared thermal imaging component, so they will not be elaborated here.

[0025] In this implementation, the serial port upload circuit is connected to the serial port tool of the computer through a USB to TTL converter. The component status is obtained by querying the TTL of the serial port detection circuit. The information returned is normally 0 and abnormally 1. The MCU will record the power-on flag as 1 and the power-off flag as 0. For example, for the visible light module, when powering on without abnormality, it is 01, 00; when powering on with abnormality, it is 01 01; when powering off, it is 00 00. The same applies to other modules. The serial port upload circuit is connected to the computer and is used to transmit the status of the multispectral device to the host computer.

[0026] The working principle of this embodiment is as follows:

[0027] The photosensitive sensor, temperature sensor, and serial port detection circuit transmit information to the MCU, and the MCU processes the corresponding information to control the power supply and components.

[0028] Utilizing the photosensitive characteristics of the photosensitive sensor, its resistance value is extremely small during the day and extremely large at night. Based on the collected voltage value, it is determined whether it is day or night. During the day, the power supplies of the infrared thermal imaging and laser illumination are turned off, and the visible light power supply is turned on. At night, the power supply of the infrared thermal imaging or laser illumination can be selected to supplement light. In this way, the three components do not need to work simultaneously during the same time period. On the basis of manual adjustment, it can also be adaptively adjusted.

[0029] The temperature sensor is used to detect whether the temperatures of the three components are normal. Within the normal temperature range, the detection frequency of the serial port detection circuit can be slower. When the detected temperature exceeds the threshold, it indicates that there is an abnormal phenomenon with the component, and the detection frequency of the serial port detection circuit should be higher to detect problems earlier. The same applies to the serial port circuit for status upload. If there is no abnormality, the upload frequency does not need to be very fast, just confirm that the device is still operating normally. If there is an abnormal situation on-site, the return frequency should be relatively higher, and it can be adaptively and selectively uploaded.

[0030] As Figure 6 shown, the working process of the present utility model is as follows:

[0031] 1. The MCU will collect the photosensitive value transmitted by the photosensitive sensor, and the MCU will determine whether it is day or night currently.

[0032] 2. If the light-sensitive value collected by the light-sensitive sensor is daytime, the MCU automatically controls the visible light power supply to turn on and uploads the on state of the visible light power supply. The status of the visible light component can be queried on the visible light serial port. The temperature sensor of the visible light component transmits the temperature value of the component to the MCU. When the temperature is normal, the query rate of the visible light serial port can be slower and the types of query error codes can be fewer. When the temperature is abnormal, more attention needs to be paid to this component, and the query rate of the serial port should be increased and the types of query error codes should be increased. When the visible light power supply is turned on, the power supplies of the infrared thermal imaging and laser illumination are turned off, so that the temperature sensors and serial port queries of the infrared thermal imaging and laser illumination components can stop.

[0033] 3. If the light-sensitive value collected by the light-sensitive sensor is night, the MCU automatically controls the power supply of the infrared thermal imaging to turn on and queries the status of the component on the serial port of the infrared thermal imaging. The temperature sensor of the infrared thermal imaging transmits the temperature of the component to the MCU. When the temperature is normal, the query rate of the serial port can be slower and the types of query error codes can be fewer. When the temperature is abnormal, more attention needs to be paid to the abnormal component, and the query rate of the serial port should be increased and the types of query error codes should be increased. When the infrared thermal imaging power supply is turned on, the power supply of the visible light is turned off to reduce resource consumption.

[0034] 4. The laser illumination component is used in conjunction with the visible light. The supplementary lighting function of the laser illumination enables the visible light to see objects clearly at night. Thus, if the visible light fails and cannot be used during the day, the infrared thermal imaging can be manually controlled to turn on directly for continuous monitoring; if the infrared thermal imaging fails and cannot be used at night, the visible light and laser illumination can be manually controlled to turn on directly for continuous monitoring.

[0035] 5. The status upload mainly includes whether the component is powered on, whether it is normal, and the error code, which allows us to directly observe the operation of the device. Under normal circumstances, the upload frequency of the status can be reduced. When an abnormality is received, the upload frequency of the status needs to be increased to play a warning role. According to the uploaded status, the usage status of the device can be adjusted in a timely manner.

[0036] The above description is only the basic principle and preferred embodiments of the present invention. The improvements and replacements made by those skilled in the art based on the present invention fall within the protection scope of the present invention.
